Description
TECHNICAL FIELD
[0001] The present invention relates to the field of power
generation technologies, and specifically to a mobile power
generation system.
BACKGROUND
[0002] The oil and gas industry generally adopts hydraulic
fracturing to promote the production of hydrocarbon wells (for
example, oil or gas wells). Conventional fracturing equipment
generally has the problems of occupying a large area, causing
severe environmental pollution and so on, failing to satisfy the
increasingly serious environmental requirements and the
requirements on the area occupied by well-site operations.
[0003] A complete set of electrically-driven fracturing equipment
will effectively reduce the discharge of environmental pollutants,
the occupied area, noise and the operation and maintenance costs.
With the use of a complete set of electrically-driven fracturing
equipment and the continuous increase of the power of
electrically-driven fracturing equipment, higher requirements are
imposed on power supply at the operation site. At the well-site,
the power supply for fracturing equipment generally cannot be
realized by using a power grid. Moreover, the fracturing operation
has the characteristic of short operation cycle, and fracturing
equipment needs to be moved among different well-sites. Generally,
because various parts of a power supply system require different
assembly, transportation and installation methods, the installation
time of the power supply system will be up to half to one
month.
[0004] Therefore, how to provide a mobile power supply system which
can be quickly and conveniently installed at the
electrically-driven fracturing operation site is currently a great
challenge for electrically-driven fracturing operations.

DESCRIPTION OF THE EMBODIMENTS
[0023] As used herein, the term "conveyance" refers to any
transportation unit, including a trailer, a truck, a skid or a
barge used for large tonnage gravity transportation.
[0024] As used herein, the term "intake chamber" can be replaced
throughout the disclosure, and is called "inlet", "air intake port"
and "intake chamber" in general. In addition, the term "exhaust
collector" can be replaced throughout the disclosure, and is called
"exhaust diffuser" and "exhaust chamber" in general.
[0025] A mobile power generation system, including a power
generation transport apparatus 100 and an intake-exhaust transport
apparatus 200, the power generation transport apparatus 100
includes a gas turbine 105, a generator 106, an intake chamber 102,
an exhaust collector 103, an auxiliary system and a first
conveyance 109; the auxiliary system is applied to the gas turbine
105 and the generator 106, the auxiliary system includes a turbine
lubrication system, a fire fighting system and a generator
lubrication system and the like. The intake-exhaust transport
apparatus 200 includes an intake-exhaust system and a second
conveyance 204, the intake-exhaust system and the second conveyance
204 are separably connected, the intake-exhaust system includes an
intake assembly 201 and an exhaust duct 202, the intake assembly
201 and the exhaust duct 202 are integrally transferred and
connected to the top of the power generation transport apparatus
100. The intake assembly 201 and the exhaust duct 202 are disposed
on a conveyance in combination, improving the ease of
transportation.
[0026] Plentiful and inexpensive hydrocarbon fuels (for example,
natural gas) at the oil and gas well-site are used as fuels for the
gas turbine 105, which transforms chemical energy of hydrocarbon
fuels to mechanical energy. Then the generator 106 transforms the
mechanical energy into electric energy, thus achieving an
efficient, stable, and mobile supply of electric energy to the
electrically-driven fracturing operation site. The intake-exhaust
system is transferred and jacked up as a whole by at least four
lifting gears 203. The mobile power generation system can implement
the quick and convenient installation and docking of a complete set
of the power generation system depending on its own lifting gears
203, without the need of additional auxiliary equipment (such as
crane, lifter, etc.), thus effectively reducing the time of
installation. The four lifting gears 203 are disposed on the four
corners of the intake-exhaust system.
[0027] The lifting gears 203 include supporting legs 205 and
retractable support mechanisms. The supporting legs 205 are
composed of vertical hydraulic cylinders 301. The extension of the
vertical hydraulic cylinders 301 bring about the jacking up of the
intake-exhaust system. The retractable support mechanisms are used
to support the intake-exhaust system, and push the vertical
hydraulic cylinders 301 outwards through their own horizontal
expansion, i.e, to implement the horizontal movement of the
supporting legs 205. When docking, the retractable support
mechanisms can retract to one side at the same time to adjust the
intake-exhaust system to move to the left or the right.
[0028] The supporting legs 205 can move outward the second
conveyance 204, and can jack up the intake assembly 201 and the
exhaust duct 202, the jack-up height of the supporting legs 205 is
greater than the height of the power generation transport apparatus
100.
[0029] The power generation transport apparatus 100 further
includes an electric power unit 107 and a control system 108, the
electric power unit 107 is configured to output electric power from
the generator 106, and the control system 108 includes a gas
turbine control unit and a generator control unit.
[0030] FIG. 1 is a top view of the external structure of the power
generation transport apparatus. As shown in FIG. 1, the power
generation transport apparatus 100 has a turbine housing 101. The
shown turbine housing 101 is provided with a ventilation intake
104, a port of an intake chamber 102, and a port of an exhaust
collector 103.

generator 106, an electric power unit 107 and a control system 108
inside the turbine housing 101; the gas turbine 105 is connected to
the generator 106, the electric power unit 107 and the control
system 108 are connected to the intake chamber 102 and the exhaust
collector 103 on the gas turbine 105. The exhaust duct 202 in the
intake-exhaust system is docked with the port of the exhaust
collector 103, and the intake assembly 201 in the intake-exhaust
system is docked with the port of the intake chamber 102.
[0032] FIG. 3 is a schematic diagram of the intake-exhaust
transport apparatus in transport state. As shown in FIG. 3, the
second conveyance 204 is provided with an intake assembly 201 and
an exhaust duct 202 concurrently. The intake assembly 201 is
configured to provide combustion air and gas-turbine-chamber
ventilation air. The intake assembly 201 includes an intake filter,
an intake silencer and a ventilation fan, the ventilation fan is
connected to the ventilation intake 104 on the turbine housing 101.
The exhaust duct 202 includes an exhaust silencer and an exhaust
stack. During transportation, the exhaust stack is sleeved outside
the exhaust silencer, i.e, the exhaust stack dose not occupy
vertical height space, the height of the whole intake-exhaust
transport apparatus 200 meets the requirements of road
transportation.
[0033] FIG. 4 is a side view of the intake-exhaust transport
apparatus in transport state. As shown in FIG. 4, the lifting gears
203 are unexpanded at that time, i.e, the supporting legs 205
neither move outward the second conveyance 204, nor jack up the
intake-exhaust system upwards. The second conveyance 204 bears the
total weight of the lifting gears 203, the intake assembly 201 and
the exhaust duct 202.
[0034] FIG. 5 is a schematic diagram of the intake-exhaust

conveyance 204 is separated from the intake-exhaust system
completely. The exhaust stack moves upwards through a lifting
mechanism, and is disposed on the top of the exhaust silencer. Due
to that the exhaust duct 202 and the intake assembly 201 are
disposed on the same conveyance closely, to avoid the exhaust from
being sucked into the intake assembly 201 after discharge, it is
necessary to elevate the distance between the exhaust stack and the
intake assembly 201. The lifting mechanism includes, but not
limited to, a hydraulic cylinder.

204 completely by the lifting gears 203.
[0036] FIG. 7 is a structural schematic diagram of the mobile power
generation system. As shown in FIG. 7, the intake-exhaust system
has been mounted on the top of the power generation transport
apparatus 100, that is, the working state of the power generation
system has been achieved to supply power to electrically-driven
fracturing sites.
[0037] FIG. 8 is a structural schematic diagram of the lifting
gears. As shown in FIG. 8, the retractable support mechanism is
configured to bear the intake-exhaust system, the retractable
support mechanism includes a supporting frame, an expansion
chamber, an expansion support 303 and a horizontal hydraulic
cylinder 302, etc. The vertical hydraulic cylinder 301 is connected
with the horizontal hydraulic cylinder 302, one end of the
expansion support 303 is connected to the vertical hydraulic
cylinder 301, and the other end of the expansion support 303 is
connected to the expansion chamber, so that the expansion support

height is greater than the height of the power generation transport
apparatus 100; moving away the second conveyance 204, and moving
the power generation transport apparatus 100 to the bottom of the
intake-exhaust system; the position of the power generation
transport apparatus 100 is adjusted on the travelling direction,
the intake-exhaust system is horizontally adjusted through the
horizontal hydraulic cylinder 302 so that the port of the intake
chamber 102 and the port of the exhaust collector 103 on the power
generation transport apparatus 100 correspond to the port of the
intake assembly 201 and the port of the exhaust duct 202
respectively; the intake-exhaust system is brought down through the
vertical hydraulic cylinder 301 in the lifting gears 203, so that
the port of the intake assembly 201 is docked with the port of the
intake chamber 102, and the port of the exhaust duct 202 is docked
with the port of the exhaust collector 103, i.e, the whole power
generation system goes into the working state.
